Description

【０００１】
【発明の属する技術分野】
本発明は、照明器具を有する飾り棚に関するものである。
【０００２】
【従来の技術】
従来から玄関等に配置される収納器具として図５に示すような照明器具５を有する飾り棚が知られている。この飾り棚は棚１を有しており、棚１の天板２の外周には壁部３が設けられている。壁部３と天板２とに囲まれた空間は上方が開口した照明器具収納部４となり、この照明器具収納部４に照明器具５を設けている。天板２には照明器具５の光を棚１の内部に採り込む採光孔部２１を設けている。
【０００３】
この飾り棚は照明器具５が人の目線よりも高く位置するように例えば天井のすぐ下等に配置される。そして飾り棚は照明器具５の光を棚１の内部に照らすことで棚１の内部及び棚１に収納されたものを美しく見せる。また目線よりも高い位置にある照明器具５は壁部３によって外周を覆われているため、飾り棚の外部より見えないようになっている。また、照明器具収納部４の上方は外部に開放されているため、ここから照明器具５の発生する熱を逃がし、照明器具５や飾り棚自体が熱くなってしまうことを防止している。
【０００４】
しかしながら、上記従来の飾り棚のように照明器具収納部４の上方に開口を有しているものは、採光孔部２１や照明器具５から漏れた光が照明器具収納部４の上部開口から照明器具収納部４の上方に漏れてしまい、飾り棚の上方の天井に光の筋等ができてしまうという問題があった。またこれを防止するために、照明器具収納部４の上方を板等で覆う方法も考えられるが、この場合、照明器具収納部４の上方は板などによって覆われるため、照明器具収納部４の放熱ができなくなってしまい、照明器具５や飾り棚自体が熱くなってしまうという新たな問題が生じてしまう。
【０００５】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、その目的とするところは、採光孔部や照明器具から漏れた光が照明器具収納部上方の開口から漏れないようにすると共に照明器具収納部の放熱を行うことができる飾り棚を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するために本発明に係る飾り棚は、棚１の天板２の外周に上方に突出する壁部３を設け、この壁部３と天板２に囲まれた空間内部を照明器具収納部４とし、照明器具収納部４に照明器具５を収納し、天板２に照明器具収納部４に収納した照明器具５の光を棚１内部に採り込むための採光孔部２１を設けた飾り棚であって、上記壁部３に照明器具収納部４の上方を覆う遮蔽板７を設け、遮蔽板７に照明器具収納部４と外部とを連通させる放熱孔８を形成し、照明器具収納部４の放熱孔８と照明器具５との間の位置に遮光部材９を設け、遮光部材９を、天板２の照明器具５と放熱孔８との間に位置する箇所に設けた上方に突出する上向き板１２と、遮蔽板７の上向き板１２と放熱孔８との間に位置する箇所に設けた下方に突出する下向き板１３とで構成して成ることを特徴とするものである。
【０００７】
上記のように照明器具収納部４の上方を覆う遮蔽板７を設けることで、採光孔部２１や照明器具５から漏れ出た照明器具５の光が照明器具収納部４の上方に漏れることがなくなり、また放熱孔８を設けることで、照明器具収納部４の熱を放熱孔８から外部へ放熱することができ、さらに照明器具収納部４の放熱孔８と照明器具５との間の位置に遮光部材９を設けることで、遮蔽板７に設けた放熱孔８からも光が漏れることを防止することができる。また光源側である天板の照明器具５側に上向き板１２を設けることで、採光孔部２１や照明器具５から漏れでた光をより多く遮ることができ、さらに遮蔽板７の放熱孔８側に下向き板１３を設けることで、放熱孔８から光が漏れることをより一層防止することができる。
【０００８】
また請求項２記載の飾り棚は請求項１記載の飾り棚において、上記遮蔽板２の後端部に切り欠き１０を設け、棚１の後面を壁１１に沿わせ、遮蔽板２の切り欠き１０と壁１１とに囲まれた孔を放熱孔８として成ることを特徴とするものである。
【０００９】
上記のように構成することで、遮蔽板７の後端部に切り欠き１０を設けるだけで飾り棚の後方の壁１１を利用して放熱孔８を簡単に形成することができ、また放熱孔８を壁１１側の後端部に設けることで、もし放熱孔８から照明器具５の光が漏れたとしても、飾り棚の正面側に光が漏れ出ることを防止できる。
【００１２】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１３】
本実施形態における飾り棚は、図１〜３に示すように前方に開口する箱状の棚１を主体として構成しており、この棚１の後面を例えば玄関の土間等の壁１１に沿わせて配置させるものである。またこの飾り棚は後述する照明器具５が人の目線よりも高く位置するように例えば天井のすぐ下等に配置されるものである。
【００１４】
棚１は水平な仕切り板１５を上下方向において複数枚有しており、これにより棚１の内部に複数段の収納部１６を形成している。なお、この棚１の仕切り板１５は後述する棚１の上方の照明器具５の光が棚１の下部の収納部１６まで届くようにガラス等の光を透す性質を有する材料で形成しても良いものとする。
【００１５】
棚１の上端部には天板２を構成しており、天板２の平面視中央部にはざぐりを有する採光孔部２１が穿孔している。この天板２には前端部に上向きに突出する前壁１８と、両側端部（天板２の外周）に２枚の上向きに突出する側壁１９とが設けられている。本実施形態ではこの前壁１８及び両側壁１９とを天板２の外周の上方に突出する壁部３としており、壁部３及び天板２に（前壁１８と両側壁１９と天板２とに）囲まれた空間内部を照明器具収納部４としている。なお上記の両側壁１９は棚１の両側板２４と一体に形成してあっても良く、また両側壁１９と棚１の両側板２４とが別体であってもよいものである。
【００１６】
上記照明器具収納部４には照明器具５が設けられている。具体的には前述した天板２の採光孔部２１のざぐりに照明器具５のカバー本体２２が取付けられており、この場合カバー本体２２に取付けられたランプのような光源（図示せず）は採光孔部２１付近に位置しており、またカバー本体２２の下端部に設けられた光源を覆う透明なセード２３は採光孔部２１の下端部開口付近に位置している。上記により棚１の内部及び棚１に収納したものを照明器具５の光によって美しく照らすことができる。また、この照明器具５は目線よりも高い位置にあり且つ前方及び側方が壁部３によって覆われているため、外部から見えないようになっている。なお、上記照明器具収納部４に収納した照明器具５の種類については限定されず、従来から使用されている種々の照明器具５を用いることができる。
【００１７】
ところで、上記の飾り棚は照明器具５の光源から発する光が採光孔部２１の縁や、カバー本体２２の放熱用の孔等から照明器具収納部４側に光り漏れを起こしてしまう。そこで本実施形態ではこの漏れた光が照明器具収納部４の上方に漏れることを防止するために、以下のような構成を有している。なお以下の説明における飾り棚は棚１の後面を壁１１に沿わせた状態のものとする。
【００１８】
前述した前壁１８及び両側壁１９の上端部には照明器具収納部４の上方を覆う遮蔽板７が設けられている。このように照明器具収納部４の上方を覆う遮蔽板７を設けることで、照明器具５や採光孔部２１から漏れた光が照明器具収納部４の上方に漏れることを防止している。
【００１９】
遮蔽板７の両側端部を除いた後端部には前方に凹む切り欠き１０を設けており、遮蔽板７の両端部の後端面は天板２の後端面と面一となっている。これによって飾り棚を棚１の後面を壁に沿わせて配置した場合、遮蔽板７の切り欠き１０の後方は壁１１によって塞がれ、壁１１と切り欠き１０とに囲まれた孔が形成される。本実施形態ではこの孔を照明器具収納部４内の熱を放熱するための放熱孔８としている。またこの場合、遮蔽板７の後端部に切り欠き１０を設けるだけで飾り棚の後方の壁１１を利用して放熱孔８を簡単に形成することができ、飾り棚のコストダウンにつながる。
【００２０】
上記飾り棚の照明器具収納部４の放熱孔８と照明器具５との間の位置には上向き板１２と下向き板１３とで構成された遮光部材９が設けられている。
【００２１】
上向き板１２は天板２の前後方向における照明器具５と放熱孔８との間に位置する箇所に上方に向かって突出しており、天板２の幅方向全長に亘って設けられている。上向き板１２の上端部は上下方向において照明器具収納部４の中央付近に位置している。
【００２２】
また下向き板１３は遮蔽板７の後端部の両側端部を除いた部分（切り欠き１０によって形成された後端面）から垂下しており、下向き板１３の先端は照明器具収納部４の上下方向における中央付近まで伸びている。つまり、下向き板１３は遮蔽板７の前後方向における照明器具５と放熱孔８との間に位置することとなる。またこの下向き板１３によって照明器具収納部４の後端部の下部には後方に向かって開口する壁側孔２０が形成される。
【００２３】
上記のように遮蔽板７に放熱孔８を設けることで、照明器具収納部４の熱は図１の矢印イに示すように壁側孔２０を通って、図４のロに示すように放熱孔８より飾り棚の上方に放熱されることとなり、照明器具５や飾り棚自体が熱くなってしまうことを防止することができる。また上記では放熱孔８を壁１１側の後端部に設けているので、もし採光孔部２１やカバー本体２２から漏れた光が放熱孔８から上方に漏れたとしても、その光は棚１の後端部上方に漏れるだけで、使用者が見ることができる棚１の前端部上方付近に光が漏れることはない。
【００２４】
また、照明器具収納部４の放熱孔８と照明器具５との間の位置に遮光部材９を設けているので、遮蔽板７に設けた放熱孔８に向かう採光孔部２１やカバー本体２２から漏れた光を遮光部材９によって遮ることができ、これにより光が放熱孔８から漏れることを防止することができる。さらに遮光部材９を上向き板１２と下向き板１３とで構成し、遮蔽板７の放熱孔８側に下向き板１３を設けることで、放熱孔８から光が漏れることをより一層防止することができ、尚且つ光源側である天板２の照明器具５側の下部に上向き板１２を設けることで、採光孔部２１や照明器具５から漏れた光をより多く遮ることができる。また上記上向き板１２及び下向き板１３は共に照明器具収納部４の上下方向の中央付近まで伸びており、これによって採光孔部２１や照明器具５から漏れた光が壁１１に直接当たることがなくなり、放熱孔８から強い光が漏れることを防止している。
【００２５】
【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、照明器具収納部の上方を覆う遮蔽板を設けることで、採光孔部や照明器具から漏れ出た照明器具の光が照明器具収納部の上方に漏れることがなくなり、また放熱孔を設けることで、照明器具収納部の熱を放熱孔から外部へ放熱することができ、これによって照明器具や飾り棚自体が熱くなってしまうことを防止し、さらに照明器具収納部の放熱孔と照明器具との間の位置に遮光部材を設けることで、遮蔽板に設けた放熱孔からも光が漏れることを防止することができる。また光源側である天板の照明器具側に上向き板を設けることで、採光孔部や照明器具から漏れでた光をより多く遮ることができ、さらに遮蔽板の放熱孔側に下向き板を設けることで、放熱孔から光が漏れることをより一層防止することができる。
【００２６】
また請求項２記載の発明にあっては、上記請求項１記載の発明の効果に加えてので、遮蔽板の後端部に切り欠きを設けるだけで飾り棚の後方の壁を利用して放熱孔を簡単に形成することができ、これにより飾り棚のコストダウンができ、また放熱孔を壁側の後端部に設けることで、もし放熱孔から照明器具の光が漏れたとしても、飾り棚の正面側に光が漏れ出ることを防止できる。
